Description
Hot rolled wire that is produced and coiled at high velocity usually presents unsuitable conditions for most NDT inspection methods and their attendant grading, marking or sorting operations. However, when it is subsequently cold drawn, possibly recoiled and later straightened, then fed into a cold header, one final and meaningful inspection opportunity exists. Although the choice of inspection method is restricted by excessive wire vibration and intermittent feed speeds encountered, in several applications a rotary probe eddy current system, offering 100% inspection, has been successfully applied.
